You will work closely with experienced maintenance personnel, Manufacturing Engineering, Manufacturing, Quality, EHS, equipment suppliers, and other cross-functional teams to convert field knowledge into standardized, documented, and sustainable maintenance systems and transition maintenance from reactive support toward systematic equipment reliability\nWhat You’ll Do:\nDevelop, implement, and continuously improve preventive and predictive maintenance programs for manufacturing equipment, facilities interfaces, and automation systems. \nMonitor equipment performance and analyze downtime, MTBF, MTTR, OEE, preventive maintenance compliance, and repeat-failure trends to identify reliability improvement opportunities. \nLead structured root cause analysis for critical, chronic, and recurring equipment failures and implement permanent corrective and preventive actions. \nManage equipment modifications and improvements through applicable company change-management and engineering review processes, ensuring changes are evaluated, approved, documented, implemented, validated, communicated, and formally closed. \nPrepare and maintain controlled engineering documentation including equipment specifications, drawings, BOMs, manuals, PM standards, troubleshooting guides, equipment history, maintenance records, validation evidence, and technical reports. \nConvert maintenance experience and field knowledge into standardized maintenance procedures, inspection checklists, troubleshooting standards, training materials, and technical documentation. \nEstablish equipment criticality and risk-based maintenance priorities focusing resources on equipment with the greatest impact on safety, quality, production, and business continuity. \nDevelop and maintain critical spare-parts strategies based on equipment criticality, failure history, component lifecycle, lead time, and production risk. \nCoordinate equipment improvement and change activities with Manufacturing Engineering, Manufacturing, Quality, EHS, suppliers, and contractors. \nSupport troubleshooting of mechanical, electrical, pneumatic, control, sensor, motor, servo, robotic, and automation equipment as applicable. \nSupport new equipment introduction including technical reviews, installation, FAT/SAT, commissioning, qualification, and formal handover into the maintenance system. \nEnsure new and modified equipment is incorporated into PM programs, spare-parts requirements, equipment documentation, training, and maintenance history before closure. \nLead or support reliability and equipment improvement projects aimed at reducing unplanned downtime, repetitive failures, maintenance response time, and operational risk. \nApply structured methodologies including RCA, 5 Whys, Fishbone, FMEA, TPM, and data-based failure analysis to maintenance and equipment problems. \nCoordinate technical activities with external equipment suppliers and contractors and ensure work, safety controls, deliverables, and documentation meet applicable company requirements. \nSupport equipment-related CAPEX and improvement projects by defining maintainability, reliability, spare-part, lifecycle, documentation, and maintenance requirements. \nPromote disciplined execution of company processes including engineering documentation, action tracking, change control, safety review, equipment validation, training, and timely action closure. \nWhat We Seek:\nBachelor’s degree in mechanical, electrical, mechatronics, automation, control engineering, or a related engineering discipline. \nMinimum 5 years of relevant experience in manufacturing equipment maintenance, equipment engineering, reliability engineering, automation, or industrial equipment support. \nPractical understanding of manufacturing equipment including mechanical, electrical, pneumatic, sensor, motor, servo, or automation systems. \nStrong understanding of preventive maintenance, equipment troubleshooting, failure analysis, and equipment reliability principles. \nDemonstrated ability to manage technical documentation, engineering changes, improvement activities, and project actions in a structured manner. \nAbility to manage engineering work from problem identification through technical review, approval, implementation, validation, documentation, training, and closure. \nStrong organizational skills and attention to documentation accuracy, follow-up, data integrity, and procedural compliance. \nEffective cross-functional communication skills with the ability to coordinate with Manufacturing, Engineering, Quality, EHS, technicians, suppliers, and contractors. \nBasic data analysis and computer skills, including Microsoft Excel and electronic maintenance or engineering records. \nStrong ownership with the ability to balance immediate equipment needs with long-term reliability and system improvements. \nOutstanding candidates will have:\nExperience with formal engineering change management, MOC, equipment change control, or equipment validation processes. \nExperience building or improving preventive or predictive maintenance programs rather than only performing reactive repairs. \nWorking knowledge of CMMS, SAP maintenance systems, equipment history databases, or other digital maintenance management systems. \nExperience analyzing MTBF, MTTR, OEE, downtime, PM compliance, and repeat-failure data. \nExperience with PLC/HMI, servo systems, industrial robots, sensors, pneumatic systems, automated manufacturing equipment, or related control technologies. \nExperience managing equipment BOMs, critical spare parts, lifecycle risks, obsolescence, and supplier technical support. \nExperience supporting equipment installation, FAT/SAT, commissioning, qualification, validation, or manufacturing release. \nKnowledge of TPM, Reliability-Centered Maintenance, FMEA, structured RCA, and continuous improvement methodologies. \nExperience in semiconductor, high-purity fluid handling, precision manufacturing, injection molding, CNC machining, automated assembly, cleanroom, or another highly controlled manufacturing environment. \nDemonstrated ability to translate hands-on maintenance knowledge into standardized systems, controlled documentation, and sustainable engineering processes.","description_format":"text","description_chars":6936,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Industrial
